JOHN SMITH HAINSWORTH, OF LONDON, ENGLAND.

AUTOMATIC VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 588,425, dated August 17, 1897. Application filed March 8, 1897. Serial No. 626,514. (No model.) Patented in England May 19, 1896,No. 10,765.

.To @ZZ whom it may concern,.-

Be it known that I, JOHN SMITH HAINs- WORTH, a subject of the Queen of Great Britain, residing at 19A Coleman Street, London, England, have invented certain new and useful Improvements in Automatic Brakes for Road-Vehicles, (patented inv Great Britain,

following is la speciiication.

This invention relates to automatic brakes for road-vehicles which are operated by back pressure of the draft-animal Aor team; and it has for its object to provide novel means for locking the pole or thill against back-sliding motion, so that whenever desired the draftanimal or team may be "backed without applying the brakes.

To accomplish this object, my invention consists in the features of construction and in the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is an under plan elevation of my apparatus with brakes affixed in position for contact with the wheels of a two-Wheeled vehicle; Fig. 2, an under plan showing the application of same to the front Wheels of a fourwheeled vehicle provided with shafts; Fig. 3, an under plan of the apparatus modified to suit the front wheels of a double-horse or four-wheeled vehicle provided with a pole or tongue; Fig. 4, a plan of the apparatus With the brakes applied to act upon the hind Wheels of a four-wheeled vehicle; Fig. 5, an enlarged view of the rollers and chain hereinafter more fully described; Fig. 6, a detached elevation of the removable stop, which can be drawn out of contact with the shaft or pole to enable the vehicle tovbe manenvered, such as when the vehicle has to be backed into a coach house. Fig. 7 is a sectional view through the center bolt.

For clearly explaining my invention I give the following description, to be read in conjunction with the annexed drawings.

A A are shaft or pole rods with lug, strap, or chain connection with the necessary part of the harness. If from a pair of shafts, as in Fig. 2, the lugs can be affixed to the saddle-loops or breeching straps or chains, and if by a pole, as at Fig. 3, to the collar.

According to Fig. 1 the shaft-rods A A of a two-wheeler are in guides B B and have secured to their inner ends short rods C C, to which are jointed the cross-rods D D to move on the pivots E E andcarry the brake-blocks FIF to press against the wheels G G when iany back action is exerted by the lugs H H,

which, as before stated, are attached to the animals saddle, loops, or breeching-straps. To Vthe shaft-rods A A the trace hooks or pins B'V B' are fixed, so that the brake is kept off when the animal tightens the traces, or, if desired, a spring may be attached to hold the brake oif.

According to the plan of the front under part of a four-wheeler (shown at Fig. 2) the shafts A A where they join onto fore carriage are attached to sliding bars A' A', these having the short rods C C affixed for operating the cross-rods D D and brakes F F against the wheels G G.

Where a vehicle has four wheels, such as a pole-van, I brake the front wheels or the hind wheels (see Fig. 3) by arranging a cap or slider J on the front end of the pole K, and by a rod A running lengthwise under the pole the pull-back or pull-up action of the animals through the collar on the pole-chains LL causes the rod A to force back the ends of the cross-rods and so'apply the brakes.

If I desire to brake the back wheel or wheels of a four-wheeled vehicle under my automatic system, I affix a pulley N and frame P under the foot-board, as shown in Fig. 4E, so that K the pulley N can swivel, and I lead a chain or cord Q or the like from the cross-bars D D, pivoted, as in the previous figures, over said pulley N, and connect it to a cross-bar R of the sliding rods C O, so that when the animals back or are pulled up they apply the brakes F F.

Toenable the under front part of the vehicle to be turned, such as into the position shown in full lines in Fig. 4, without putting strain or twist on the chainor cord Q, I secure two guide-pulleys to the frame P, into the groove of either of which the chain or cord can engage, according to whether the turning be to the right or to the left.

To enable the vehicle to be backed or the frontV under carriage of a four-wheeled vehicle to be turned, as usual, I providea locki ing device M for locking the pole or the thills against back-sliding motion relatively to the body or running-gear of the Vehicle. The locking device M, as here shown, is composed of a transversely-slidable rod mounted in suitable bearings on a part of the vehicle and constructed to slide in engagement with the pole or the thills, whereby the latter are locked against slidinI motion. either backward or forward, and consequently the Vehicle may be backed to amT required extent Without applying the brakes. The locking device M can be controlled from the side of the vehicle, or it may be provided with a stud T, Fig. G, within reach of the driver. In either event the locking device is susceptible of being instantly operated to disengage the pole or thills and thus enable the brakes to be .ap-- plied when descending an incline.

Fig. 7 is a sectional View through the eenter bolt, showing that the mechanism for applying the brake by the foot-Spud a. is effectual with the under body in any position, as the connecting-rod h passes through the pivotal center e, upon which said under carriage turns, and consequently does not alter its relation thereto. The rod ZJ is formed as a swivel.

Where desired for long or steep gradients a catch may be fixed which can he moved by the driver to keep the brake on as long as he Wishes.

That I claim, and desire to secure by Letters Patent, isn

In a road-vehicle, the Combination with pivoted levers having brake-shoes, and a longitudinally-sliding pole, or thill connected with the brake-levers and operated by back pressure of the draft animal, or animals te apply the brakes,oi` a transVersely-movable lockingrod constructed to engage the pole, or thill and lock the saine against baclesliding niotion, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
